Cameras were configured with the lens they came with and set in automatic AGC mode. Light was set to a level then each camera was tested, then the light was changed and the cameras retested. Initial test was with the flourescent lights on. The light meter read 300lux +/-50lux (position and pose sweep of the area). The light meter is uncalibrated and only useful for relative testing in brighter conditions. All additional tests were conducted with LEDs (cool white) on a high quality HP linear DC power supply. 3.5lux test - light meter read +/-0.3lux. Light meter did not handle low light much below this point. Low1 test - light meter read 0, it was dark and I could just barely make out the target squares were different colors, but not what color and spinning motor. Low 2 test - about 50% less illumination than low1, I could not see the motor spinning and I could just make out the outer rectangle of the target but not the color squares.
